Looking at cruises and one disembarks in San Juan... now my ? is.. is there a direct flight from San Juan to Boston? It;s going to be a trans-atlantic and the one ship we are interested ends up in P.R.
Be aware that Puerto Rico is considered to be part of the United States for purposes of customs and immigration. Thus, you'll clear U. S. immigration and customs during disembarkation from the ship. The flight to San Juan to the mainland operates as a domestic flight, so you don't have to reclaim your luggage to clear customs if your preferred airline requires a connection. Also, if you book on one of the airlines that offers nonstop service from San Juan (SJU) to Boston (BOS), you'll arrive at the airline's normal terminal rather than at the International Terminal (currently Terminal E) at Logan.
